Red lightning bolt of death

[Zane2014]

I have had my 2014 V6 for almost 7 years it has been moderately reliable, minus the oil cooler blowing a couple years back. Now out of the blue right before I am supposed to move it gets the red lightning bolt of death. Just happened out of the blue, if I am driving it will randomly go into limp mode and the dash will light up like a Christmas tree with every error message known to man popping up. Seems to happen more on rough roads but really just random. My first thought was a faulty TIPM but after replacement it still is happening. Checked wiring harnesses doing wiggle tests for hours. Checked grounds. Having done weeks researching and trying to diagnosis I haven't gotten much of anywhere. Anyone have a crazy electrical gremlins like this before and find a fix? Any help is much appreciated, driving me absolutely crazy. Just a laundry list of CAN bus and implausible data. I have autel scan tool which usually helps but these rams seem to be very finicky.

Here is a list of the codes.

ABS (Anti Lock Brakes) – 4 DTCs:

1. U0401-00 – Implausible data received from ECM/PCM (Stored)
2. C121C-00 – Torque request signal denied (Stored)
3. U0002-88 – CAN C bus off performance - bus off (Stored)
4. C2100-16 – Battery voltage low – circuit voltage below threshold (Active)

ORC (Air Bag/Occupant Restraint) – 1 DTC:

2. U0002-00 – CAN C bus off performance (Stored)

How old is your battery?

Test if, or have it tested.

 

[Zane2014]

One of first things I did was test the battery and alternator. Battery is new, and alternator is reading correct voltage. I have heard of ABS module issues in these trucks but it seems to be a victim of whatever problem is going on rather than the cause.

It looks like the canbus system is down for some reason. Possibly a short to ground somewhere or a broken connector.

Check the big BCM connector under the driver side footwell, up above the parking brake area. IF that big cam lever on the BCM connector breaks or comes loose, you will loose the network and have pretty much everything throw codes like that.

Check other connectors too. Anything that is on the canbus system, like the electronic power steering, transmission, the pcm connectors. Especially anything that gets wet (not sure if you're in the rust belt, no profile location). Or, any connectors that could get hit by road debris.

Did you load test the battery W/ Toaster style tester, Harbor Freight has them, your new battery may be bad, with all of those DTC low voltage may be your problem, are you able to clear any of those codes, majority of the ABS problems have been on the HD 2500 and up.

Hey William,

The $18 battery load tester link at HF has been buggered for weeks now.

I use the following link that shows several testers and direct users to the $18 unit.

To the OP, this direction is spot on and a classic fault we see here very often.

One flakey cell in a battery will make our truck's computer modules go completely bonkers.

There are only 2 conditions for 12V batteries, proven by toaster-style load tester or unknown. New is irrelevant.

I should qualify all of this by stating, the fault is common to many modules, most likely power related and starting with the primary DC power source, is the standard protocol.

Troubleshooting electronic systems is not a guessing game but a systematic analysis with a defined starting point.

In this system, the rolling microcomputer or your truck, the starting battery is a common point of failure connected to the entire network.

Don’t want to leave anyone wondering. After some more wire hunting it ended up being the Engine Oil temp sensor wiring. Might not help everyone but might help someone.

The engine oil temperature sensor wiring caused that DTC storm? Wow!

Thanks for the update.

It was the tb on my 04 5.7. That made the bolt go off.

 

[Rado]

I had similar issue as well on my 2015 1500 w/Pentastar !
Was my throttle body !
Good to have extra info

 

[Jeepwalker]

Was that oil temp wire shorted to ground? Or another wire? That's strange it would do all that!!

What was wrong? Was the wire shorted to ground?????

Yes, please elaborate.

I had the same issue years ago on my 06 Hemi truck. I had 3 whites that had shorted out on the passenger side against the exhaus. Bought new ECM computer & alot of other useless parts they tried to bill me for. Let's just say the garage ****** themselves. Because I didn't wind up paying for nothing for getting the truck repaired. Me & the garage owner came to a mutual understanding because of friends in low places....

Can you elaborate? Been having the same problem for two days

The OP was only here for 4 days and hasn't been seen since late May.

Troubleshooting electronic systems is not a guessing game but a systematic analysis with a defined starting point.

What is the next step after checking the battery?

My error codes are:
P2122 Throttle/Pedal Position Sensor/Switch 'D' Circuit Low
P0522 Engine Oil Pressure Sensor/Switch 'A' Low
P0335 Crankshaft Position Sensor 'A' Circuit
P0642 Sensor Refernce Voltage 'A' Circuit Low
P018D Fuel Pressure Sensor 'B' Circuit High
U1428 Received Engine Torque Request Signal Stuck
P0520 Engine Oil Pressure Sensor/Switch Circuit Malfunction
P2111 Throttle Actuator Control (TAC) system - actuator stuck open
P1618 Sensor Reference Voltage 1 Erratic
C121C-00 Torque Request Signal Denied
U0401-00 Implausible Data Received From EMC/PCM 'A'

So far I've replaced the throttle body, accelerator pedal, replaced battery and checked it with the toaster style tester, and cleaned the MAF sensor. All of which made no difference still getting the same codes.

 

[Jeepwalker]

Almost sounds like the OP's oil press wire must have been shorted.

Your issue IDK. Have you pushed down all your truck's fuses in case some are lifted up? And I'd probably wiggle and inspect the bundle of wires & connectors below the TIPM. There have been other owners who've had corroded pins and even badly corroded wires behind the TIPM connectors. There have been a few owners who needed to replace connector pins and splice out wires at the connectors. If nothing else, if you haven't done so, it would be worth a visual inspection of the TIPM connectors & pin to rule it out.


I'm just tossing out ideas, I don't know what your specific issues is. Sucks to have them. Hope you find them soon.

As stated above, I'd be looking at fuses, and checking every one of them with a test light to confirm power at both ends of the fuse.

Next thing I'd do is look around for damaged or corroded wiring. Maybe you've got a mouse in there somewhere. That's too many codes to be just one thing. I removed a fuse one time and forgot to reinstall it, and when I restarted the truck, it gave me a list of troubles similar to that.

If you load tested the battery with a toaster style battery load tester, it gets a pass.

With the absolute DTC storm that you are experiencing, there's a possibility that you have a locked on module spewing crap out onto the CAN bus.

You may have to play the isolation game, unplugging power to individual modules, and then testing if your DTC storm has cleared.

They may not clear just by unplugging the foul module, you may have to reinitialize the whole communication bus.

We often see this kind of storm with a bad battery as well. Hopefully you have used a toaster style battery load tester for your testing.
